This invention relatesto improvements in mechanical movements and moreparticularly to power transmitting mechanism, and the particular objectthereof is the provision of 1 an .efiicient means of transmitting powerto a driven shaft, whereby the shaft may be driven in either directionwithout requiring the 'medium of a clutch or other similar device. Allgears are dispensed with, and the control of the direction of rotationof the driven shaft is accurate and complete in each direction.

A further obj ect of this invention is the provision of means fortransmitting power to the Wheels of a self-propelled vehicle withoututilizing a differential.

A further object of this invention is the provision of means forlockingthe deviceand preventing rotation of the shaft when the parts arein an intermediate position.

Further objects of this invention include improvements in details ofconstructionand arrangement, whereby an efficient and simple mechanismof this character is provided.

To the accomplishment of the foregoing and such other objects as mayhereinafter appear, this invention consists in the construction,combination, and arrangement of parts hereinafter described and thensought to be defined in the appended claims, reference being had to theaccompanying drawing forming a part hereof,-and which shows merely forthe purpose of illustrative disclosure, a preferred embodiment of myinvention, it being expressly understood, however, that various changesmay be made in practice within the scope of the claims withoutdigressing from my inventive idea.

Referring now to thedrawing, the numeral 1 designates a support in whichthe driven shaft 2 is rotatablymounted. A cylindrical rotary member orrotor 3jis keyed, or otherwise secured, to the driven shaft 1, therotary member or rotor being'provided on its circumference with aplurality of spaced notches or cut-away parts 4: extending the fullwidth of the rotor 3. Each notch or cut-away portion% is formed with afiat bottom portion perpendicular-to a diameter of the rotor, and withthe sides of the notch perpendicular to thefflat bottom portion.

If the parts are reversed it is to be noted that the notches 4 will beaccordingly changed and may or may not be provided onthe pcriphery ofthe rotor. They are'symmetrical- I 1y arranged, however.

Mounted within each notch or cut-away portion 4 is a pair of-cylindricalrollers 5. It is to be expressly understood, however, that elementsother than rollers may be employed, such as ball bearings, for instance.These rollers 5 have a diameter smaller than the maximum depth of thenotches or cutaway portions. Spaced bands or rings 6 and 7 are slightlylarger in diameter than the rotor .3, and form housing means for rollers5. These rings (Sand 7 are loosely mounted on the rotor 3, andco-operate with rollers 5 to cause the'rollers to become wedged be!tween the rings and'the rotor and cause rotation of the shafts. Byhaving rollers 5 of M,

smaller diameter than the" depth of the notches, it is possible to holdthe rollers out of wedging contact with the rings 6 and '7 whenever itis desired. Lug 8 provided on the top of ring 6, and lug 9,:provided onthe bottom of ring 7 are adapted for attach- ,ment to links 10 and 11,which links, in turn, are pivoted to a reciprocating member 12. Othermeans for actuating the rings Band 7 may be used. It is to beekpresslyjunder- 1 a tures l8. lihe position given to the side plates 15and 16 by this movement, places the spindles 20 so that the rollers 5are free to drop downward on theleft side of the rotor to be wedgedbetween the rotor 3 and rings 6 and 7, and the rotation of the rotor andshaft must follow in the direction indicated in Figure 1. It is to benoted that the rollers 5 on the ri ht side of the rotor are held up outof wedging relation between the rings 6 and 7 and the rotor 3.

In Figure 4 pins or rods 19 are shown intermediate the ends of openings17 and apertures 18. The pins or rods 19 have been moved to thisposition by the interengaging of one of the rods 19 shown at the extremeright in Figure 1 with the eccentric grooves 33 of the locking arms 23and 2t. Side plates 15 and 16 have also been turned a certain angle, andhence spindles 20 have been moved so that a wedging action between rings6 and 7 and rotor 3 is obtained by positioning rollers 5 between therotor 3 and the rings 6 and 7 on the left and right sides of the rotor.In this position, the device is locked and no movement is obtained.

In Figure 5 pins or rods 19 have been moved to the outer ends ofopenings 17 and apertures 18 and side plates 15 and 16 have been givenan additional movement. Spindles 20, due to their connection with saidplates 15 and 16 by means of openings 21 and 22, have been placed in aposition to allow rollers 5 on the right side of the rotor to drop downand be wedged between rotor 3 and rings 6 and 7 so as to cause rotationof the rotor and driven shaft in a direction opposite to that shown inFigure 1. It is to be noted that the rollers 5 on the left side of therotor are held up out of wedging contact, and that the position of theparts shown in Figure 1 is exactly opposite to that shown in Figure 5,and rotation of the driven shaft is obtained in the opposite direction.

When the device is used to transmit power in a self-propelled vehicle,no differential is required. A split axle isused and when one part oftheaxle moves faster than the other, as when the vehicle is turning acorner, a running-ahead is permitted by the vehicle.

' The fact that the device allows the axle to run-ahead of the enginespeed, gives the further advantage that whatever momentum the car maygain will be added to the engine speed, with the result that the carspeed may be greater than the engine speed. In the cars now in use, withthe engine in gear, the car cannot travel faster than the engine, andthe momentum of the car is, therefore, lost.

It will be apparent that-I have provided a relatively simple devicewhich will function to transmit power and rotate a shaft in eitherdirection without using a clutch or similar device, and which can beused to propel 2. ve-
